It is common for people to report one or more of the following symptoms:
- Dryness and irritation of the eyes, nose, throat, and skin
- Shortness of breath
- Hypersensitivity and allergies
- Sinus congestion
- Coughing and sneezing
People generally notice their symptoms after several hours at work and feel better after they have left the building or when they have been away from the building for a weekend or a vacation.
Many of these symptoms may also be caused by other health conditions including common colds or the flu, and are not necessarily due to poor IAQ. This fact can make identifying and resolving IAQ problems more difficult.
